GROUP PROJECTS!!!!

Pre-class preparation questions:•what is design?•what bothers you most about having to work in groups to learn and accomplish projects? •what have you found to be helpful about working in groups?•how would you define team-based learning?•what are characteristics of an engineering design team?•what are roles and responsibilities of group members?•what are possible solutions to typical problems encountered in group learning?

what is design?

I. client

II. end-requirement of effluent and residuals

X

work backwards

considering all design variables

to arrive at solution

I client

II. end-requirement of effluent and residuals

design variables?

wastewater constituents

policy and regulations

septic tank design

sanitation and public health concerns

conveyance system

treatment technologies

drainfield technologies

intended reuse of effluent

nutrient removal

wastewater effects ecological impacts of constituents

site evaluationsoils, groundwater, slope, available

land, etc

treatment capacity of soils

climate

operations and maintenance

economic situation

social preferences

client demands

what else???

Problem ScopingProblem definition – criteria and constraints

Information gathering – facts and data to solve problem

Developing Alternative SolutionsGeneration of ideas and concepts

Modeling – estimating measurementsFeasibility analysis – judgment of workability

Evaluation of alternatives – e.g. matrix

Project RealizationDecisions - specifying elements

Problem Solving Methodology

Problem Solving Methodology

Project RealizationSolution of the problem

Communication of the results

II. what bothers you most about having to work in groups to learn and accomplish projects?

III. what have you found to be helpful about working in groups?

IV. how would you define team-based (vs. group) learning?

Discussion questions…

I. design variables and relevant concern for onsite or decentralized

Results of research on team projects show members:

•obtain higher levels of understanding•develop ability to “use” course concepts

(apply to problem solving and decision making)•learn more about how to learn•develop skills for working effectively on a team•appreciate value of team approach for solving complex tasks

Why are we working on team projects?

What are characteristics of an engineering design team?

small group of peoplecomplimentary skill set committed to common purposeemploying common approach….

….that they are mutually accountable for!!!!

What are roles and responsibilities of group members?

•technical expertise•personal preferences •team coordinator•individual roles•sub-teams

Social Loafing

Research says…….…….top two considerations for building successful teams are:

Group does not:•require individual accountability•call for input from each group member•reward members for group work•provide regular feedback

People are:•naturally shy•dominators of discussions•not confident in their knowledge•not committed to team success•bashful about appearing disagreeable•not convinced problem is complex enough to require entire group

Team Cohesiveness

•be respectful•get to know each other•organize tasks, goals, and roles•delegate work•divide leadership role amongst the group members•collaboratively determine next steps•be able to rely on team members to complete their task•meet regularly to communicate information to team members

Keys to success in team projects?

Accountability – peer assessment

Introduction to group projects:

1. Merrill Hall, University of Washington Campus

2. Jiuzhaigou National Park, Sichuan Province China

3. Hood Canal, Puget Sound, Washington State

Natural Area

May 21, 2001, an arsonist placed a gasoline bomb in Professor Toby Bradshaw’s office

Rebuilt with LEED certification Interconnectivity of

•water•natural resources•manufactured materials•people, knowledge and action

Low flush toilets, waterless urinals and grade of pipe to sewer result in solids settling and clogging pipe

The UW has hired you to evaluate and design an onsite wastewater treatment and reuse system for Merrill Hall that fits in with the existing structures and the original project goals. In addition to key aspects that you identify, the following must be considered in your report to the UW:

1. treatment system requirements 2. installation and space requirements3. ability to handle diurnal flows and seasonal school

schedule flows4. operational and maintenance requirements5. approximate cost of installation and operation6. acceptability to faculty, staff and students7. area needed for effluent storage, reuse8. how system will be managed9. potential for environmental education

Jiuzhaigou National

Park

“The Valley of Nine Villages”

The only park in China to have the combined certifications of UNESCO World Heritage Site, World Biosphere Reserve, and Green Globe 21

Tourists are only allowed access to the park on an extensive boardwalk network and via the parks bus transportation system

Current tourist system:•high operating costs•insufficient human and environmental health protection•resource intensive requirements

JNP has a goal in place to replace the sanitation and toilet system

The administration of JNP has hired you to evaluate and design a sanitation and toilet system for the tourists. In addition to key aspects that you identify, the following must be considered in your report to JNP:

1.protect the environment of JNP 2.footprint3.more economical system4.reliability5.ease of maintenance6.sanitation and hygiene7.aesthetics8.usability9.environmental education10.beneficial reuse11.park capacity

Hood Canal 60-mile long fjord in the Puget Sound

Map taken from Hood Canal Dissolved Oxygen Program

Experiencing seasonally decreasing levels of dissolved oxygen (DO)

Nitrogen sources potentially contributing to the problem:•septic systems•fertilizers from residential use and commercial forestry•pets•alder trees

The Puget Sounds Action Team has hired you to develop two options for a cluster of 22 homes currently on septic systems to consider:

1.each individual homeowner upgrade to a recommended individual onsite treatment method

2.the entire development upgrades to a recommended alternative for a clustered treatment system

The following must be considered in your report to the PSAT on the two alternatives

1. the treatment system must reliably produce an effluent that is sufficiently low enough in nitrogen for protection of the Hood Canal

2. installation and space requirements3. ability to handle diurnal and seasonal flows4. operational maintenance requirements5. relative cost difference between the on-site and decentralized system6. acceptability to homeowners7. area needed for effluent dispersal8. ownership and management of the cluster system 9. potential for funding or subsidies to aid the homeowners in upgrading
